An electric precipitator for regularly cleaning dust

technical field

The utility model belongs to the technical field of electric dust removal devices, in particular to an electric dust removal device for regularly cleaning dust.

Background technique

Electrostatic dust removal is a dust collection method that uses an electrostatic field to ionize the gas so that the dust particles are charged and adsorbed to the electrode. In the strong electric field, air molecules are ionized into positive ions and electrons, and the electrons encounter dust particles in the process of rushing to the positive electrode, so that the dust particles are negatively charged and adsorbed to the positive electrode for collection. In the past, it was often used in coal-fueled factories and power stations to collect coal ash and dust in the flue gas.

Dust is attached to the surface of the positive plate of the existing electrostatic precipitator, and the dust is collected. As the thickness of the attached dust increases over time, the efficiency of collecting dust on the positive plate will be reduced. Therefore, it is necessary to collect the dust on the upper part of the positive plate. The cleaning work is carried out regularly, the work process is complicated, and the labor intensity is high, which is not conducive to the reduction of labor costs and the long-term use of the electrostatic precipitator.
